5.3 Description of Function Codes 5.3.1 F codes (Fundamental functions)
Torque limiter levels specified via communications link (S10, S11)
The torque limiter levels can be changed via the communications link. Communication dedicated codes S10, S11
interlock with the function codes F40, F41.

F42 = 0: V/f control without slip compensation
Under this control, the inverter controls a motor with the voltage and frequency according to the V/f pattern specified
by function codes. This control disables all automatically controlled features such as the slip compensation, so no
unpredictable output fluctuation occurs, enabling stable operation with constant output frequency.
If running multiple motors, select this control method.
